This study presents a multimethod strategy to quantify citrate ligands on iron oxide nanoparticles using TGA, CHN, qNMR, and RP-HPLC, showing how selective methods improve accuracy and prevent overestimation.

IOCB Prague scientists have developed light-driven molecular motors that remain fully functional even when anchored to metal surfaces, marking a major step toward controllable nanoscale machines.

Regenerating liver redirects ammonia metabolism to fuel de novo pyrimidine synthesis, enabling cell proliferation and tissue repair after hepatectomy through metabolic reprogramming.

A new class of trisubstituted pyridines targets ATP synthase in Acinetobacter baumannii. Four lead compounds showed potent antibacterial effects and synergized with colistin against multidrug-resistant strains.

A semisynthetic method enabled the preparation of stable isotope-labeled ergot alkaloids for precise HPLC-MS/MS quantification.

Suspect screening using LC- and GC-HRMS identified 547 chemicals across environmental, food, and human samples. Pharmaceuticals, pesticides, and personal care products were the most frequent contaminants.

Czech researchers developed carbon-dot nanosensors that precisely measure pH inside living cells. The technology offers stable, calibration-free fluorescence detection for biomedical use.

A VESI-MS strategy allows real-time monitoring of redox processes, enabling rational pulse design for selective decarboxylative hydroxylation using only O₂, water, and carbon electrodes.

A sustainable synthesis combining mechanochemistry and chemical aging yields defect-rich bismuth oxide nanosheets with excellent adsorption and photocatalytic performance toward persistent organic pollutants.

Researchers developed a compact, disposable 3D-printed “Lab-on-a-Scalpel” for on-site chemical analysis during surgery. The device detects biomarkers like epinephrine with high sensitivity.
